These were Lyle and Clayton, and they, or their attorney at law, or their attorney in fact, were alone legally entitled to demand and receive the money from the defendant. The case is in a court of law, where, in general, only legal interests are regarded. Jones v. Blackledge, 4 N.C. 342; Arrington v. Horne, 4 N.C. 435. The defendant was under no legal obligation to pay the money to the relators, and his refusal to do so was no breach of his bond for which they can sue.
